Use Jinja2 template engine in webpy

Problem

How to use Jinja2 (http://jinja.pocoo.org/2/) template engine in webpy?

Solution

You need to install both Jinja2 and webpy(0.3) first, and then try out the following code snippet:

import web
from web.contrib.template import render_jinja

urls = (
        '/(.*)', 'hello'
        )

app = web.application(urls, globals())

render = render_jinja(
        'templates',   # Set template directory.
        encoding = 'utf-8',                         # Encoding.
    )

# Add/override some global functions.
#render._lookup.globals.update(
#       var=newvar,
#       var2=newvar2,
#)

class hello:
    def GET(self, name):
        return render.hello(name=name)

if __name__ == "__main__":
    app.run()

Template file: templates/hello.html

Hello, {{ name }}.
